Contrails now appear sooner on wingtips by +40-50Kph

This is just to make people aware that some time in the last few months gaijin changed the threshold to where contrails on wing tips appear.

This is meaningful if you are trying to stall an enemy out (rope a dope) or hide your energy state. that extra 40-50Kph has been surprising me in game with the enemy having more energy than I anticipated. I felt that any one else might find this info useful in future engagements.
